Bad slow motion is probably the more ubiquitous: you see it all the time on television. Essentially, it’s done by frame doubling a normally shot loop of video. In other words, if something was shot at thirty frames per second, each frame is shown twice so that a ten second clip lasts twenty seconds. It looks blurry and stilted. You see this a lot in television shows that are trying to hide how terribly choreographed an action scene is.

Then there’s good slow motion. It requires filming at a higher FPS rate to begin with. When you play it at a normal twenty four frames per second, what you get is incredibly clear and fluid. When you see a slow-motion shot of, say, a bullet piercing an apple, you’re looking at slow motion done with an appropriate lens.

Vision Research’s Phantom Flex camera masters in good slow motion. It can capture 1080p video at an astonishing 2,800 frames per second with 1000 ISO sensitivity. If that doesn’t cut if for your needs, it can shoot at 2,560 x 160 at 1,560 frames per second, or at VGA resolution at 13,000 frames per second.

Since the Phantom Flex will slurp up an 8GB SD card in a blink of an eye at those rates, it features swappable SSD modules for storage, and will even film in stereoscopic 3D.

How much does it cost? Unknown, but with these specs, more than an amateur can afford.
